A lot of folks want a map to Staff Engineer, and just as many Staff Engineers want to better understand their role. Towards that end, I'm working on a small project to collect folks' stories of reaching and operating as staff-plus engineers

"What should I measure when the CEO asks for engineering metrics?" is probably the most frequently recurring eng leadership question, and connects into a larger, somewhat nebulous topic: how should you measure engineering organizations? Some notes!

A core management skill is bridging between your management’s and your team’s expectations in a way that is authentic to both’s values. If you never say no to your team, you’re not actually managing them. If you never change your management’s mind, you’re not being a manager.
